Bjorken polarized sum rule and infrared-safe QCD couplings
Abstract Experimental data obtained for the polarized Bjorken sum rule (BSR) $$\Gamma _1^{p-n}(Q^2)$$ Γ1p-n(Q2) are fitted by using predictions derived within a truncated operator product expansion (OPE) approach to QCD. Four QCD versions are considered: perturbative QCD (pQCD) in the $${\overline{\...
